I-CDSR Dreding Hosses zihlala zisetyenziselwa ukuthutha intlabathi, udaka kunye nezinye izinto ezikwiiprojekthi ze-offshore, ziqhagamshelwe kwinqanawa yokufakelwa okanye izixhobo zokudlulisela indawo echongiweyo ngenjongo okanye ukukhutshwa. I-Horeding Hosses idlala indima ebalulekileyo ekulondolozelweni kwezibuko, ukwakhiwa kweenjineli zaselwandle, ukuntywila kwemilambo kunye namanye amasimi, ukubonelela ngenkxaso eqinileyo yokugcina iindlela ezigudileyo kunye nokhuseleko lwendalo emanzini.
Ukubala rhoqo
Umjikelo we-Dreding: Umjikelezo we-Dreding ubhekisa kwixesha lokwenza umsebenzi wokuqhuba. Ngokweempawu zesibuko okanye indlela yendlela kunye notshintsho kubunzulu bamanzi, umjikelo ohambelana nobuphindiso uya kwenziwa ngokubanzi.
Uhlalutyo lwedatha: Hlalutya imeko kunye neirhafu ze-sediment kwi-ports okanye iindlela zamanzi ngokusekwe kwiirekhodi zembali, idatha ye-hydrological, intshukumo ye-sediment kunye nenye idatha.
Indlela ye-Dreding: Ngokwezakhono zezinto ezibonakalayo kunye nezakhono zobugcisa zezixhobo zedanti, khetha indlela efanelekileyo yokuchonga kunye nenkqubo yokufumanisa ivolumu yeprojekthi kunye nokusebenza kakuhle kwenkqubo.
Iziphumo zokubala iziphumo zendlela yokuqhuba i-Dreding lixabiso eliqikelelweyo, kwaye ixabiso elithile kufuneka lihlengahlengiswe ngokusekwe kwiimeko zokwenyani kunye neemfuno zobunjineli. Kwangelo xesha, ubalo lwe-rareding frequency kufuneka lubekelwe iliso rhoqo kwaye luhlaziywe ukuqinisekisa ukuba iimeko zokuhambisa izibuko okanye indlela yokuhlangana ifezekisa iimfuno.
I-Dereding Draquency
Idrafti engekhoyo
Iindlela ezinzulu zenzululwazi (engaphantsi kweenyawo ezingama-20) zinokwenza i-dired yokuthoba yonke iminyaka emihlanu ukuya kwesixhenxe
Izinto ezichaphazela i-frequency frequency
Imeko engqongileyo:I-aluplations ye-toploor yaselwandle kunye neenguqu kubunzulu bamanzi ziya kubangela ukuba ukuqokelelwa kweeSedonts, ukwenziwa kweesanti, njlnjl..Ngelixa iiSandbars zenziwa ngokulula elwandle kufutshane neziqithi. Ezi meko zejografi ziya kukhokelela ekubeni kuncitshiswe indlela yendlela, efuna i-direding rhoqo ukugcina indlela yamanzi icocekile.
Ubuncinci obunzulu:Ubuncinci obusezantsi kubhekisa kubunzulu bamanzi obuncinci ekufuneka bugcinwe kwisitishi okanye kwizibuko, elihlala limiselwa yidrafti yenqanawa kunye neemfuno zokhuseleko lokuhamba. Ukuba i-sediment Seddation ibangela ukuba amanzi abe nobunzulu bamanzi angaphantsi kobunzulu obusezantsi, inokunyusa umngcipheko kunye nobunzima bokuhamba ngenqanawa. Ukuze kuqinisekiswe ukuhamba nasekukhuselekileyo kwejelo, irejista ye-direding ifuna rhoqo ngokwaneleyo ukugcina ubunzulu bamanzi ngaphezulu kobunzulu bamanzi ngaphezulu kobunzulu bamanzi.
Ubunzulu bunokutshiswa:Ubunzulu obunokutshiswa bubunzulu obungaphezulu kwe-sediment enokususwa ngokufanelekileyo zizixhobo zedarethi. Oku kuxhomekeke kubuchule bezixhobo zobugcisa bezixhobo zedanti, njengokumba umda wobunzulu be-Dredge. Ukuba ubukhulu be-sodiment bungaphakathi kuluhlu olunzulu oludanisiweyo, ukusebenza kwe-dareding kunokwenziwa ukubuyisela ubunzulu bamanzi afanelekileyo.
Igcwalisa njani le ndawo:Ireyithi apho i-sediment igcwalisa le ndawo yireyithi apho i-sediment iqokelela kwindawo ethile. Oku kuxhomekeke kwiipateni zokuhamba kwamanzi kunye nezantya zothutho lwe-sediment. Ukuba i-sediment igcwalisa ngokukhawuleza, inokubangela ijelo okanye izibuko ukuze libekho ngexesha elifutshane. Ke ngoko, i-frequech efanelekileyo kufuneka iphakanyiselwe ngokusekwe kwireyithi yokugcwalisa i-sediment ukugcina ubunzulu bamanzi afunekayo.
